1.8 KiB
1.8 KiB
Pre-release
- Commands to list constants, units, and substitutions
- list and delete variables
- sin() with units (rad and deg)
- Re-evaluate variables (a = q + 2, q = 3, a should evaluate to 5)
- 2x^-1 as superscript
- Celsius and Farenheit
Parser
- Better error when
sin = 2 - Define functions (f(x) = ??)
- Should functions be operators?
- Multi-argument functions
General
- Optional config file
- Optional history file
- Compile to WASM, publish a webapp
- Options:
- disable replacement
- disable special characters
- 1/ as -1 power toggle
- powers as superscripts toggle
- evaluate straight from command line
- Auto-push to crates.io
Internals
- Non-recursive treeify
- Faster factorial function. Maybe use gamma instead?
- Arbitrary precision float (rug doesn't offer arbitrary exponents)
- Remove rug dependency (too big, incompatible)
Math Features
- Function definitions
- Dice
- Mean, Median, Min
- Arbitrary base logarithm
- Derivatives
- CAS features (trig, roots and powers)
- Complex numbers
- acot/acoth functions
- Binary, hex, octal numbers
- Extra roots? (for convenience)
- Sums and products with functional arguments
Prompt
- Live syntax/output (like firefox js terminal)
- Syntax highlight input and output
- fish-style tab completion
- Numbered expressions, history recall
- Color configuration
- Enable/disable unit sets (defaults?)
- Consistent unit ordering
- Better linelocation
- we shouldn't need to re-print user input on evaluation errors, red arrows should adjust themselves to the prettyprinted string
- Backend-independent colorful printing
- Better colors in error texts
Units
- long prefixes (megatonne, etc)
- HMS for degrees
- Exact radians, using pi constant?
- Weird units: flops, lumen, lux, bel
- Plural unit names
- More constants
